What range do you have now? How big is your tank? What is you GPH consumption now?
Most people establish fuel rules like 1/4 there, 1/4 back, 1/4 trolling, and 1/4 reserve. I think some use 1/3 rule not sure.
I for one will be buying a fuel flow meter to establish range, GPH, economy, etc. A wise investment for just over a hundred bucks.
What are others with similar boats doing? What is their range?
I just checked the MS website and here's what it said about your model:

Performance with maximum horsepower is outstanding. Top speeds consistently in the 45 MPH range have been recorded with 3-5 persons on board, and good cruising speeds of 20-30 MPH are common with RPM's as low as 3500. Further testing with mid-range 130-150 HP engines showed the hull to be very fuel-efficient. Top speeds with 130-150 four-strokes ranged between 35 MPH to 43 MPH. At 24 MPH, the boat had a cruising range of over 260 miles.
Hey...is this similar to your boat?
if so...cool ride man!
